The Lowdown

Alright folks, Rusty here. Let’s look at what’s on offer for the next couple of weeks at Jaconé.

We’ve got a solid run of surf kicking off, but it’s not all clean sailing. The first few days bring some decent size, but you’ll need to pick your sessions carefully for the best conditions.

Thursday morning, September 3rd, is the real standout of the entire forecast. Jaconé is seeing a clean 7 ft swell from the S, with a moderate offshore wind from the ENE that’s going to keep the faces smooth. The combined energy is up there at 992 – that’s a good, solid push of power. The period is 11 seconds, a proper groundswell, which means nice shaped lines. The water is sitting at 73°, which is about normal for this time of year. This is the best wave you’ll see in the window.

The afternoon of the 3rd sees the wind swing more easterly and pick up, making it cross-off and a bit messier. It’s still surfable, but not as good as the morning.

Friday morning, the 4th, the swell drops to 4 ft from the SSE. The wind is light from the NNE, almost glassy, so it’ll be clean and fun on the smaller waves, but it’s a big step down in power from Thursday.

After Friday, the swell goes quiet for a few days. The 5th and 6th are small and weak, with lumpy, choppy conditions on Saturday, and onshore winds ruining it on Sunday morning – that’s a real gap in the quality.

Things pick up again on Monday, September 7th. The morning brings a clean 6 ft swell from the S (energy of 458) with a light cross-off breeze. That’s a solid, surfable day. The afternoon builds to 7 ft of S swell, but it gets a strong cross-shore chop, making it messy.

Tuesday the 8th holds in the 6 ft to 7 ft range from the S/SSE, offering a clean morning (energy of 825) and another clean afternoon (energy of 1098). The wind is a moderate cross-off, so it’s not glassy, but it’s plenty surfable and the power is there.

The swell backs off a bit on Wednesday the 9th, with the wind becoming strong offshore, making it clean but the waves are smaller and the energy drops.

Thursday, September 10th, is another promising afternoon. The swell is 5 ft from the E, with a light wind making it clean. The energy is 609, so it’s got some push. This is a good, clean option later in the first week.

The following week, from the 11th to the 13th, the swell stays small, with waves mostly under 4 ft and light winds. It’s clean, but small – a grovel board session.

There’s a long lull then, with nothing to write home about until Monday, September 14th, which brings a very long-period 16-second swell from the S, but it’s 4 ft and the wind is onshore, so it’s a complete write-off. The rest of the second week is a mix of small, messy, or onshore conditions. The only real flicker of hope is Wednesday, September 16th, which has a glassy 2 ft S swell in the morning, and then a clean 3 ft E swell in the afternoon.

To wrap it up: If you want the best wave, you’re on the water Thursday morning, September 3rd. That’s the one. The 7th and 8th are your next best bet for some proper size and clean conditions. The second week is a write-off for anything decent.

Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
